This paper describes a case study of an online physics laboratory course implemented for 254 engineering students at Walailak University in Thailand in response to the COVID-19 pandemic. The laboratory sequence was designed based on the United Kingdom Professional Standards Framework and covered eight experiments on fundamental concepts of motion, electricity, waves, and fluid mechanics. The experiments were conducted at students' homes using physics education technology simulations, Tracker for video analysis, smartphones, and home-based apparatuses. During the experiments, students shared their progress with classmates and lecturers through screen sharing, which facilitated exchanges of ideas and difficulties. The paper discusses the successful implementation of the online laboratory course and the challenges encountered, such as student engagement, resource limitations, and practical skill development. The insights gained from this case study may be useful for online laboratory education beyond the pandemic.
